FIG. 1 is a diagram illustrating a surveillance system 10 according to an exemplary embodiment.

Referring to FIG. 1, the surveillance system 10 includes an internal network device 100, a gateway 200, an external network 300, a server 400, and a user terminal 500.

The surveillance system 10 may be provided as a configuration in which, when information regarding the internal network device 100 is collected by the gateway 200 and transmitted to the server 400 over the external network 300, a manager monitors the information transmitted to the server 400 using the user terminal 500.

The internal network device 100 may include one or more internal network devices. The internal network device 100 may include, but is not limited to, a mobile battery camera 100A, a stationary battery camera 100B, a sensor 100N, etc.

The mobile battery camera 100A and the stationary battery camera 100B may capture surveillance areas to acquire images of the surveillance areas. The mobile battery camera 100A and the stationary battery camera 100B may capture the surveillance areas in real time for the purpose of surveillance or security.

The surveillance area of the mobile battery camera 100A may be changed according to an installation location of the mobile battery camera 100A. For example, when the mobile battery camera 100A is placed on a flat surface, the mobile battery camera 100A may continuously capture a certain surveillance area. When the mobile battery camera 100A is placed on an upper portion of the gateway 200, the mobile battery camera 100A may horizontally capture a surveillance area while rotating from side to side due to the rotation of the upper portion of the gateway 200. When the mobile battery camera 100A is installed on a wall or a ceiling by a fixing module, the mobile battery camera 100A may capture a certain surveillance area at a certain angle.

The mobile battery camera 100A may be a zoom camera that has a lens with an adjustable zoom magnification. The mobile battery camera 100A may enlarge or reduce a surveillance area by adjusting the zoom magnification of the lens.

The mobile battery camera 100A may be a low-power camera driven by a battery. The mobile battery camera 100A may operate in a normal mode or a charging mode depending on whether the battery is being charged. The mobile battery camera 100A may include a rechargeable battery 1011 (see FIG. 3) and a non-rechargeable battery 1012 (see FIG. 3). In the charging mode, the rechargeable battery 1011 (see FIG. 3) may be charged with power supplied by the gateway 200. In the normal mode, at least one of the rechargeable battery 1011 (see FIG. 3) and the non-rechargeable battery 1012 (see FIG. 3) may be drained.

In the normal mode, the mobile battery camera 100A may usually maintain a sleep mode and may periodically wake up to check whether an event occurs. When an event occurs, the mobile battery camera 100A may be switched to an active mode to acquire an image. When no event occurs, the mobile battery camera 100A may return to the sleep mode. Thus, when the mobile battery camera 100A is operating in the normal mode, the mobile battery camera 100A may discontinuously acquire images.

In the charging mode, the mobile battery camera 100A may acquire images regardless of whether an event occurs. In other words, when the mobile battery camera 100A is operating in the charging mode, the mobile battery camera 100A may continuously acquire images. In this case, the mobile battery camera 100A operating in the charging mode may acquire images in real time.

The images acquired by the mobile battery camera 100A operating in the normal mode may be low-quality images, while the image acquired by the mobile battery camera 100A operating in the charging mode may be high-quality images. At least one of a frame rate, a resolution, and a bit rate of such a high-quality image may be higher than that of such a low-quality image.

As such, when the mobile battery camera 100A is being charged, it is possible to intensify surveillance by acquiring high-quality images from the mobile battery camera 100A. When the charging of the mobile battery camera 100A is stopped, it is possible to reduce power consumption by maintaining the active mode of the mobile battery camera 100A only when an event occurs.

A surveillance area of the stationary battery camera 100B may be fixed. For example, when the stationary battery camera 100B is installed on a wall or a ceiling by a fixing module, the stationary battery camera 100B may capture a certain surveillance area at a certain angle.

The stationary battery camera 100B may be a pan tilt zoom (PTZ) camera that is capable of panning and tilting and has a lens with an adjustable zoom magnification. The stationary battery camera 100B may change surveillance areas depending on the panning or tilting. Also, the stationary battery camera 100B may enlarge or reduce a surveillance area by adjusting the zoom magnification of the lens.

The stationary battery camera 100B may be a low-power camera driven by a battery. The stationary battery camera 100B may usually maintain the sleep mode and may periodically wake up to check whether an event occurs. When an event occurs, the stationary battery camera 100B may be switched to the active mode. When no event occurs, the stationary battery camera 100B may return to the sleep mode. In this way, the stationary battery camera 100B may reduce power consumption by maintaining the active mode only when an event occurs.

The sensor 100N detects a change in a sensing area. The sensing area may refer to an area other than the surveillance areas that are captured by the mobile battery camera 100A and the stationary battery camera 100B. The sensing area may include the surveillance areas captured by the mobile battery camera 100A and the stationary battery camera 100B and the area other than the surveillance areas. For the purpose of surveillance or security, the sensor 100N may detect whether an event occurs in the sensing area in real time. When an event occurs, the sensor 100N may generate an event detection signal and transmit the generated event detection signal to the gateway 200.

The sensor 100N may include an infrared sensor, an audio sensor, a motion sensor, a gas sensor, a leak sensor, a temperature sensor, a humidity sensor, an acceleration sensor, a gyro sensor, a tactile sensor, a pressure sensor, a vibration sensor, etc.

The internal network device 100 may communicate with at least one of another network device 100 and the gateway 200 using various communication methods such as wired/wireless local area network (LAN), Wi-Fi, ZigBee, Bluetooth, Near Field Communication (NFC), etc. For example, the internal network device 100 may communicate with the gateway 200 according to a low-power wireless communication protocol that uses a radio frequency of an industrial scientific medical (ISM) band.

The gateway 200 may be connected to the internal network device 100 in a wired or wireless manner. Thus, the gateway 200 may recognize a state of the internal network device 100 on the basis of information transmitted from the internal network device 100 and may transmit a command or a notice to the internal network device 100 or the user terminal 500 according to the state of the internal network device 100.

The gateway 200 may supply power to the internal network device 100, such as the mobile battery camera 100A.

The gateway 200 may transmit information to the server 400 and receive a command from the server 400 using various wired/wireless communication methods such as Ethernet, Wi-Fi, and Bluetooth.

The external network 300 may include a wired network or a wireless network.

The wireless network may be a 2G or 3G cellular communication system, a 3rd Generation Partnership Project (3GPP) system, a 4G communication system, a Long-Term Evolution (LTE) system, or a World Interoperability for Microwave Access (WiMAX) system.

The server 400 may transmit a notice to the user terminal 500 on the basis of information transmitted from the gateway 200 over the external network 300. For example, the server 400 may transmit a danger detection alarm to the user terminal 500 on the basis of information regarding an event detected by the sensor 100N and information regarding images acquired by the mobile battery camera 100A.

The server 400 may transmit the command transmitted from the user terminal 500 to the gateway 200 over the external network 300. For example, the server 400 may transmit, to the gateway 200, a command for sounding a siren included in the internal network device 100.

The user terminal 500 may display or store the information transmitted from the server 400. For example, the user terminal 500 may display a notice transmitted from the server 400. The user terminal 500 may include at least one or more processors. The user terminal 500 may be driven while included in another hardware device, such as a microprocessor or a general computer system. The user terminal 500 may be a personal computer or a mobile terminal.

The mobile battery camera 100A included in the surveillance system 10 will be described in detail below with reference to FIGS. 2, 3, 4A, and 4B.

FIG. 2 is a block diagram showing a configuration of the mobile battery camera 100A included in the surveillance system 10 according to an exemplary embodiment.

FIG. 3 is a block diagram showing a configuration of a battery 101 included in the mobile battery camera 100A according to an exemplary embodiment.

FIGS. 4A and 4B are diagrams illustrating of the configuration of the mobile battery camera 100A according to an exemplary embodiment.

Referring to FIGS. 1 and 2, the mobile battery camera 100A includes the battery 101, a sensing module 102, a camera module 103, a first connector 104, a first network module 105, a first processor 106, and an encoder 107.

In the surveillance system 10 including the mobile battery camera 100A and the gateway 200, the mobile battery camera 100A includes the battery 101 configured to supply power to the mobile battery camera 100A, the camera module 103 configured to capture a surveillance area to acquire images, the first connector 104 configured to directly connect to the gateway 200, the first network module 105 configured to communicate with the gateway 200, and the first processor 106 configured to operate the mobile battery camera 100A in the charging mode when the first connector 104 is connected to the gateway 200 and operate the mobile battery camera 100A in the normal mode when the first connector 104 is disconnected from the gateway 200. In the charging mode, the battery 101 receives power from the gateway 200 through the first connector 104, and the camera module 103 continuously transmits images to the gateway 200 through the first connector 104. In the normal mode, the camera module 103 discontinuously transmits images to the gateway 200 through the first network module 105.

The battery 101 supplies power to the mobile battery camera 100A.

For example, when the mobile battery camera 100A is operating in the sleep mode, the battery 101 may supply power to at least one of the sensing module 102, the first network module 105, and the first processor 106. When the mobile battery camera 100A is operating in the active mode or the charging mode, the battery 101 may supply power to at least one of the sensing module 102, the camera module 103, the first connector 104, the first network module 105, the first processor 106, and the encoder 107.

Referring to FIGS. 1 and 3, the battery 101 of the mobile battery camera 100A includes at least one of the rechargeable battery 1011 and the non-rechargeable battery 1012.

The rechargeable battery 1011 may be charged with power supplied from the outside. When the first connector 104 is connected to the gateway 200, the rechargeable battery 1011 may receive power from the gateway 200 through the first connector 104. The rechargeable battery 1011 may be charged one or more times. The rechargeable battery 1011 may be replaceable.

When the first connector 104 is connected to the gateway 200, the rechargeable battery 1011 may supply power to the mobile battery camera 100A. That is, the mobile battery camera 100A may receive power from the rechargeable battery 1011 in the charging mode.

When the first connector 104 is disconnected from the gateway 200, the rechargeable battery 1011 may supply power to the mobile battery camera 100A. When the first connector 104 is disconnected from the gateway 200 and a battery charge level of the non-rechargeable battery 1012 is less than a reference charge level, the rechargeable battery 1011 may supply power to the mobile battery camera 100A.

The non-rechargeable battery 1012 may be replaceable.

When the first connector 104 is disconnected from the gateway 200, the non-rechargeable battery 1012 may supply power to the mobile battery camera 100A. That is, the mobile battery camera 100A may receive power from the non-rechargeable battery 1012 in the normal mode.

When the first connector 104 is disconnected from the gateway 200 and a battery charge level of the rechargeable battery 1011 is less than a reference charge level, the non-rechargeable battery 1012 may supply power to the mobile battery camera 100A.

Referring back to FIGS. 1 and 2, the sensing module 102 detects an event. The sensing module 102 may include an infrared sensor, an audio sensor, a motion sensor, a gas sensor, a leak sensor, a temperature sensor, a humidity sensor, an acceleration sensor, a gyro sensor, a tactile sensor, a pressure sensor, a vibration sensor, etc. When an event is detected, the sensing module 102 may generate an event detection signal.

The camera module 103 may capture a surveillance area to acquire an image.

The camera module 103 may acquire a high-quality image in the charging mode and may acquire a low-quality image in the normal mode.

In the normal mode, the camera module 103 may capture images only when an event is detected by the sensing module 102. In the charging mode, the camera module 103 may continuously capture images regardless of whether an event occurs.

Thus, the camera module 103 may transmit the images to the gateway 200 in the normal mode only when an event is detected by the sensing module 102 and may transmit the images to the gateway 200 in the charging mode in real-time streaming.

The camera module 103 may include image sensors, such as a charged coupled device (CCD) sensor, a complementary metal oxide semiconductor (CMOS) sensor, etc.

The camera module 103 may perform a zoom-in operation to enlarge an image of an object to be captured. For example, when an event is detected in the surveillance area by the sensing module 102, the camera module 103 may perform the zoom-in operation on an object to be captured.

The camera module 103 may perform a zoom-out operation to enlarge a capturing range. For example, when an event is detected in a sensing area other than the surveillance area by the sensing module 102, the camera module 103 may perform the zoom-out operation.

The first connector 104 is a module that electrically connects to the gateway 200. For example, the first connector 104 may be electrically connected to the gateway 200 by coming into contact with a second connector 204 (see FIG. 5) of the gateway 200. In this case, the first connector 104 may include a magnet to be directly connected to the gateway 200 by an attractive force between the magnet and a magnet included in the second connector 204 (see FIG.

5) of the gateway 200. Accordingly, it is possible to increase battery charging efficiency and it is also possible to accurately capture an event that occurs in a surveillance area by predetermining a direction of the lens of the mobile battery camera 100A positioned on the gateway 200.

In the charging mode, through the first connector 104, it is possible to charge a power source of the mobile battery camera 100A simply and efficiently and to intensify surveillance by transmitting high-quality images acquired by the mobile battery camera 100A to the gateway 200, the server 400, or the user terminal 500 in real time.

Referring to FIGS. 1, 4A, and 4B, the camera module 103 may be positioned on a side surface of a cylindrical mobile battery camera 100A. When a user puts the mobile battery camera 100A on a flat surface positioned opposite the surveillance area, the camera module 103 may capture the surveillance area in front of the camera module 103.

The first connector 104 may be positioned on a bottom surface of the cylindrical mobile battery camera 100A, as shown in FIG. 4B. The user may electrically connect the mobile battery camera 100A to the gateway 200 by bringing the first connector 104 provided on the bottom surface of the mobile battery camera 100A into contact with the second connector 204 (see FIG. 6) provided on a top surface of the gateway 200.

When the first connector 104 and the second connector 204 are electrically connected, an operation mode of the mobile battery camera 100A may be switched to the charging mode. That is, the mobile battery camera 100A may charge a battery and transmit high-quality images to the gateway 200 through the first connector 104 and the second connector 204.

The first connector 104 may be a pin-type connector. For example, the first connector 104 may be a pogo pin connector. A direction in which the mobile battery camera 100A is connected to the top surface of the gateway 200 may be determined according to a shape of the first connector 104, for example, a shape of the pogo pin connector.

The first connector 104 may include magnets M11 and M12. For example, the first connector 104 may include a pair of magnets M11 and M12 at both sides of the pogo pin connector. The first connector 104 may be directly connected to the gateway 200 by an attractive force between the magnets M11 and M12 and magnets M21 and M22 (see FIG. 6) included in second connector 204 in the gateway 200. The direction in which the mobile battery camera 100A is connected to the top surface of the gateway 200 may be determined according to the shape of the first connector 104, for example, the positions of the magnets M11 and M12.

The mobile battery camera 100A may output a notification when the electrical connection with the gateway 200 is successful. For example, the mobile battery camera 100A may output a beep sound through a speaker indicating that the mobile battery camera 100A is appropriately connected to the gateway 200. The mobile battery camera 100A may display that an electrical connection with the gateway 200 is successful by outputting a green light through a notification lamp. Whether the mobile battery camera 100A and the gateway 200 are appropriately connected may be determined by whether the connection direction of the mobile battery camera 100A and the gateway 200 matches a predetermined connection direction.

When a user places the mobile battery camera 100A on the top surface of the gateway 200 positioned opposite a surveillance area, the camera module 103 may horizontally capture the surveillance area while rotating from side to side due to the rotation of the upper portion of the gateway 200. Referring back to FIGS. 1 and 2, the first network module 105 is a module that communicates with another internal network device 100 or the gateway 200. For example, the first network module 105 may transmit at least one of battery information, event information, and images of the mobile battery camera 100A to the gateway 200. The battery information may be information associated with a battery charge level. The event information may include an event type, an event detection position, etc.

In the normal mode, the first network module 105 may discontinuously transmit images acquired by the camera module 103 to the gateway 200. For example, in the normal mode, the first network module 105 may transmit images acquired through the camera module 103 to the gateway 200 when an event is detected.

The first network module 105 may receive a command from the gateway 200.

The first network module 105 may perform a communication function of at least one of wired/wireless LAN, Wi-Fi, ZigBee, Bluetooth, NFC, etc.

The first processor 106 controls overall operation of the mobile battery camera 100A.

The first processor 106 may determine an operation mode of the mobile battery camera 100A according to whether the battery is being charged.

The first processor 106 may allow the mobile battery camera 100A to operate in the charging mode when the mobile battery camera 100A and the gateway 200 are electrically connected, and may allow the mobile battery camera 100A to operate in the normal mode when the mobile battery camera 100A is electrically disconnected from the gateway 200.

The first processor 106 may activate the rechargeable battery 1011 in the charging mode and activate the non-rechargeable battery 1012 in the normal mode.

The first processor 106 may activate the rechargeable battery 1011 in the charging mode and may activate the rechargeable battery 1011 or the non-rechargeable battery 1012 on the basis of the battery charge level of the rechargeable battery 1011 in the normal mode. That is, in the normal mode, the first processor 106 may activate the rechargeable battery 1011 when the battery charge level of the rechargeable battery 1011 is greater than or equal to the reference charge level and may activate the non-rechargeable battery 1012 when the battery charge level of the rechargeable battery 1011 is less than the reference charge level.

The first processor 106 may activate the rechargeable battery 1011 in the charging mode and may activate the rechargeable battery 1011 or the non-rechargeable battery 1012 on the basis of the battery charge level of the non-rechargeable battery 1012 in the normal mode. That is, in the normal mode, the first processor 106 may activate the non-rechargeable battery 1012 when the battery charge level of the non-rechargeable battery 1012 is greater than or equal to the reference charge level and may activate the rechargeable battery 1011 when the battery charge level of the non-rechargeable battery 1012 is less than the reference charge level.

The activation of the rechargeable battery 1011 may refer to an activation of a charging function and a power supply function of the rechargeable battery 1011, and the activation of the non-rechargeable battery 1012 may refer to an activation of a power supply function of the non-rechargeable battery 1012.

The first processor 106 may control the camera module 103 to continuously acquire high-quality images in the charging mode and may control the camera module 103 to discontinuously acquire low-quality images in the normal mode.

The first processor 106 may control the camera module 103 to continuously transmit the high-quality images to the gateway 200 through the first connector 104 in the charging mode and may control the camera module 103 to discontinuously transmit the low-quality images to the gateway 200 through the first network module 105 in the normal mode.

The first processor 106 may control the encoder 107 to encode an image acquired through the camera module 103 at a low compression ratio in the charging mode and may control the encoder 107 to encode an image acquired through the camera module 103 at a high compression ratio in the normal mode.

Referring to FIGS. 1, 2, and 7, when the mobile battery camera 100A is powered on (S101), the mobile battery camera 100A determines whether the rechargeable battery 1011 is being charged (S103). The mobile battery camera 100A may frequently determine whether the rechargeable battery 1011 is being charged while the mobile battery camera 100A is powered on.

The rechargeable battery 1011 may be charged by power received from the gateway 200 through the first connector 104.

When the rechargeable battery 1011 is being charged, the mobile battery camera 100A is switched to the charging mode and acquires high-quality images (S105). In S105, the mobile battery camera 100A may acquire the high-quality images.

In this case, the mobile battery camera 100A may be connected to the gateway 200 to change a surveillance area thereof from side to side according to a panning operation of the panning module 202 of the gateway 200.

When the rechargeable battery 1011 is not being charged, the mobile battery camera 100A is switched to the normal mode and detects an event (S107).

In S109, the mobile battery camera 100A may be switched to the active mode according to an event detected by the mobile battery camera 100A itself or an event detected by another internal network device 100.

An operation of the gateway 200 included in the surveillance system 10 will be described in detail below with reference to FIGS. 8, 9A, and 9B.

FIG. 8 is a sequence diagram illustrating an operating method of the surveillance system 10 according to an exemplary embodiment.

FIGS. 9A and 9B are diagrams illustrating a panning operation of the gateway 200 according to an exemplary embodiment.

Referring to FIGS. 1, 2, 5, and 8, when the first connector 104 of the mobile battery camera 100A and the second connector 204 of the gateway 200 are connected (S201), the gateway 200 charges the rechargeable battery 1011 of the mobile battery camera 100A through the first connector 104 and the second connector 204 (S203).

That is, when the first connector 104 of the mobile battery camera 100A and the second connector 204 of the gateway 200 are electrically connected, the mobile battery camera 100A and the gateway 200 operate in the charging mode, and power is supplied from the gateway 200 to the mobile battery camera 100A through the first connector 104 and the second connector 204.

The mobile battery camera 100A operating in the charging mode acquires high-quality images (S205) and transmits the acquired high-quality images to the gateway 200 (S207).

In this case, the images acquired by the mobile battery camera 100A may be continuously transmitted from the mobile battery camera 100A to the gateway 200 through the first connector 104 and the second connector 204.

The panning module 202 of the gateway 200 may perform a panning operation according to a control signal (S209). That is, the gateway 200 operating in the charging mode may activate the panning module 202. The control signal may be an event detection signal that is received from the mobile battery camera 100A.

When the stationary battery camera 100B, which is different from the mobile battery camera 100A, detects an event (S211) and transmits an event notice to the gateway 200 (S213), the panning module 202 of the gateway 200 performs the panning operation according to an event detection signal of the stationary battery camera 100B (S209).

The stationary battery camera 100B may communicate with the gateway 200 over an internal network when the stationary battery camera 100B is not electrically connected to the gateway 200. That is, the stationary battery camera 100B may transmit an event notice to the gateway 200 over the internal network.

In this case, the stationary battery camera 100B acquires low-quality images in response to the detected event (S215) and discontinuously transmits the acquired low-quality images to the gateway 200 (S217).

When the user terminal 500 receives a user input associated with rotation of the panning module 202 of the gateway 200 (S219) and transmits a panning command corresponding to the user input to the gateway 200 (S221), the panning module 202 of the gateway 200 performs the panning operation according to the user input (S223).

The panning module 202 of the gateway 200 may rotate at a predetermined speed. In this case, the panning module 202 may rotate continuously or periodically. Alternatively, the panning module 202 may temporarily rotate by a predetermined angle according to a control signal. The panning module 202 may rotate in an original direction a predetermined time after rotating the predetermined angle. For example, the panning module 202 may rotate by the predetermined angle in a clockwise direction, and then may rotate by the predetermined angle in a counterclockwise direction after the predetermined time.

Referring to FIGS. 2, 5, 9A, and 9B, when the mobile battery camera 100A is placed on the gateway 200 and the second connector 204 of the gateway 200 comes into contact with the first connector 104 of the mobile battery camera 100A, the gateway 200 may rotate the panning module 202, for example, in the counterclockwise direction and may change the surveillance area of the mobile battery camera 100A.

As described above, according to exemplary embodiments of the present invention, since the mobile battery camera 100A is freely moved, unlike the stationary battery camera 100B, it is possible for a user to freely select a surveillance area using the mobile battery camera 100A.

Also, according to exemplary embodiments of the present invention, since the rechargeable battery 1011 of the mobile battery camera 100A may be recharged by only connecting the mobile battery camera 100A to the gateway 200, it is possible to continuously supply power to the mobile battery camera 100A.

Also, according to exemplary embodiments of the present invention, it is possible to intensify surveillance by receiving high-quality images from the mobile battery camera 100A in real time while charging the rechargeable battery 1011 of the mobile battery camera 100A.

Referring back to FIGS. 1, 2, 5, and 8, when the first connector 104 of the mobile battery camera 100A and the second connector 204 of the gateway 200 are disconnected from each other (S225), the mobile battery camera 100A and the gateway 200 operate in the normal mode, and the supply of power to the mobile battery camera 100A through the first connector 104 and the second connector 204 is stopped.

The mobile battery camera 100A operating in the normal mode acquires low-quality images (S227) and transmits the acquired low-quality images to the gateway 200 (S229).

In this case, the images acquired by the mobile battery camera 100A may be discontinuously transmitted from the mobile battery camera 100A to the gateway 200 through the first network module 105 of the mobile battery camera 100A and the second network module 205 of the gateway 200.

The panning module 202 of the gateway 200 operating in the normal mode may be deactivated. That is, the panning module 202 of the gateway 200 may stop rotating.

The gateway 200 operating in the normal mode may communicate with the internal network device 100 through the second network module 205 and may communicate with the server 400 or the user terminal 500 over the external network 300.

According to exemplary embodiments of the present invention, it is possible to efficiently use limited resources by receiving, while charging of the rechargeable battery 1011 of the mobile battery camera 100A is stopped, only low-quality images when an event is detected.

According to exemplary embodiments of the present invention, it is possible for a user to freely select a surveillance area by moving a camera included in the surveillance system.

Also, the surveillance system 10 according to exemplary embodiments of the present invention is more economical because a surveillance area may be expanded using a limited number of cameras.

Also, it is possible to conveniently and continuously supply power to a camera by simply charging a battery of the camera.

Also, it is possible to intensify surveillance by receiving high-quality images from a camera while charging a battery of the camera.
